Original application filed March 22, 1923,'Seria1 No. 628,934. Divided and this application filed November 5, 1923,.

To all whom it may concern:

Be it known that I. Hanna? W'. S'rnn'rzbeen, a citizen of the United States, and

clare the following to be a full, clear, and

exact description. of the invention, such as will enable others skilled in the art to .vlnch it appertains to make and use the same.

Ill)

This invention relates to improvements in car coupling; devices, this application being divisimi of application for patent tiled by d. C. Whitridge, G. T. Johnson, H. W. Erltertzbach and H. ."Voltt'e March 22, 1923 and designated by Serial No. 626,934.

An object of the present intention is to provide simple and efficient connecting dcices between an. M. C. B. automatic car coupling and a coupler of the hook type, which shall be flexible and not interfere with the butting action when the cars come i'zonet-her.

With this and other objects in view, the invention consists in certain novel features of construction and combinations oi: parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a plan view showing an embodi ient of my invention;

ure 2 is a side elevation of the structure shown in Figure 1, and Figure 3 is a view-on the line 3 -3 of I Figure 1.

In the drawings, an M. C. B. automatic coupling is represented at 1 and a coupler of the hook type is indicated at 2.

The connecting devices between these two types of couplings includesa U-bolt or link 3 which enters a slot 4 in the knuckle 5 of the automatic coupling and the upper and lower walls of said slot are made curved as at 6. The knuckle is made near its free end with a vertical hole which intersects the slot 4 and through this hole and the U-bolt or link 3, a pin 7 is passed. 7

The free ends of the lJ-bolt arms are in serted through suitable holes near respectiveends of a yoke or bridge 8 and then upset to form heads 9. The yoke or bridge 8 consists of a bar inserted between the body and bill of the hook coupling 2, and is made Serial Nm 672,835.

with notches in its upper and lower edges in its central portion forming a reduced intermediate portion. and providing: stops l0 and 11 to engage the sides of the body and bill of the hook and prevent transverse movement of the yoke.

When the cars come together, the U-l'JOit will slide past the pin 7 into the hollow body of the M. C. B, drawhead, while the inner wall of the hook coupling tends to slide the yoke forwardly on the U-bolt without aminino; any of the parts.

Han inc; :tully described my invention vvhat I claim as new and desire to secure by Letters-Patent, is

1. In a device oi the class described, the combination of a hook coupler, an automatic coupler including a knuckle and a pin n'iounted vertically in the free end portion of the knuckle, the knuckle having a hori zontal recess across which the pin passes, a U-bolt fitted slidably in said recess and about the pin, and a LLbolt and engaged through the hook coupler and with the sides of the said coupler.

In a device of the class described, the combination of an automatic coruiling having a knuckle provided with a vertical hole near its free end and a notch or recess in its free end and intersecting; said hole, and means for connecting; said knuckle with a hook coupling); such connecting means comprising an approximately tl-shaped member to enter the notchor recess in the knuckle and a cross member connecting and slidable upon the arms of said approximately lJ-shaped member, said cross member adapt ed to engage the hook coupling, and a pin to pass through the vertical hole in the knuckle and through said approximately tl-shaped member.

3. In a device of the class described, the combination of an automatic coupling having a knuckle provided witha vertical hole near its free end and a notch or recess in its free end and intersecting said hole, and means for connecting said knuckle with a hook coupling, such connecting means comprising; an approximately U-shaped member to enter the notch or recess in the knuckle and a cross member connecting the arms of said approximately U-shaped member, said cross member adapted to engage thev book yoke slidably fitted on the oupling, said cross member having; a re- In testhnony whereofl havesigned this duced mtermedmte portlon whereby stops speclficatmn m the presence of two subscnhare mended to be chsposed n1; respectn'e 111g Witnesses.
